Not a new topic but

I have a nizo pro camera in absolute perfect working order and when I bought it only 6 weeks ago it came with 4 carts of Kodak plus X BnW reversal 7276. Having never used this camera im assuming that it will shoot the film with no problem but in the back of my mind im still a little unsure if I should use any filters Am I also correct that this film should be shot at 100 ASA due to the new processing.

Just to add, I have been all over the search facility on the forum but ive found nothing that definitively answers my Q.

Thanks guys from a relative beginner in the film world.

The Nizo Pro camera has a build in TTL light meter. It will compensate automatically the exposure with different filters for B&W films.
You must switch off the build in 80A filter of the camera when you shot with b&w film.
If you don't trust the light meter of your Nizo, you could find out how to get the correct exposure with filters on this link.

correction,
the build in filter is 85a, the switch is on the side of the camera which is with the drawing of a sun and a lamp.
after switch off the filter, you will be able to set up the aperture manually.

The camera will sense the cartridge properly. You would need to ask the intended lab what they will do with old plus-x film. I.e. process as 50 or 100. If it becomes 100 in their chemistry you would need to squeeze the exposure one stop. BW film outdoors are best exposed using a yellow or even orange filter too bring some contrast and get rid of the empty white skies. Then you exposure might be correct automaticly! Or use the internal daylight filter which is a kind of orange too

There are many people have been talking about the build in filter that it is not a good idea to use them, they are probably either dirty or blurred.
So the safest way is to switch off them.

A PlusX cart will disable the filer but you have to set the switch on "daylight" for it to read it as 100ASA. This not enable the filter because the cart disables it already.

Thank you guys for your replies so far..........how would this camera be with 100D or 64T?

100D is just like PlusX, set it on daylight and will read 100ASA with filter automatically disabled. 64T will register 40D/64T like it should.

Thank you.

Processing:

These are the FAQs from Kodak when the new process was introduced:
http://web.archive.org/web/200611131444 ... msQA.jhtml

In short, Plus-X 7276 should be rated as 100ASA for the current process as you said.

Exposure:

You can have a look at the technical data sheet here: http://www.super8.nl/file/7276.pdf

This is how you should normally rate 7276:

Daylight — EI 50/18°
Tungsten — EI 40/17°

This how the super 8 box will tell you to rate it:

Daylight (with filter)* - EI 32/16°†
Tungsten (without filter)* - EI 40/17°

*See camera instruction manual for insertion and removal of the filter
†Automatic cameras will expose this film at EI 25/15°

The effective speed of 32ASA in this case is because a Super 8 camera's 85 filter causes 2/3 of a stop light loss. 50ASA - 2/3 stop = 32ASA. You are just compensating for the filter by telling the camera the film is 2/3 of a stop slower (32ASA) than it is.


This super 8 cartridge doesn't have a filter notch, so the Nizo Pro will disable the filter for both the daylight and tungsten positions of the filter switch.

The Nizo Pro is automatic, so it will read the film at the speed it mentions above (†) - both are without filter:

Daylight (without filter)* - EI 25/15°†
Tungsten (without filter)* - EI 40/17°

To rate it at 100ASA you need to take a light reading, then set the camera to manual exposure and then stop down the lens. You can use either setting, but your manual exposure must be relevant to whatever setting you used to take the light reading:

Using the Daylight setting: -2 stops
Using the Tungsten setting: -1 & 1/3 of a stop
e.g if light reading is f/8 then you'll move the needle to 1/3 of the way between f/11 and f/16 - this will give you 1 & 1/3 less light

Alternatively you could notch hack it to the required notch size for 100D. This will help:

Thanks for those great chunks of info there Mortron. And thanks to all others who have helped.
